The sum of the angle measures of any triangle is 180 degrees. suppose that one angle in a triangle has a degree measure of 4x+10 and another has a degree measure of 3x+5 . write an expression for the degree measure of the third angle in the triangle.

4x+10 + 3x+5 +y =180

solve for y  y=third angle

combine like terms

7x+15+y =180

subtract 7x+15 from each side

y = 180 -(7x+15)

y = 180 -7x-15

y = 165 -7x

The third angle equals 165-7x

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72

answer: 5
